CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

1. EXECUTIVE SUMMARY

ContextThe City of Salisbury is located on the northern fringes of Adelaide, South Australia. It has an estimated population of 136,0001 people and encompasses an area of 158 km². The population is forecast to grow to 146,000 (7.4%) by 2031.

The Street Trees ServiceThe Street Trees network comprises approximately 76,000 street trees.

These infrastructure assets have not historically been recorded in the asset register or capitalised. Starting in 2014/15 Street Trees will be capitalised on a project (per street) basis as a part of the Streetscape Renewal program.

The Approach

For Park & Streetscape assets, three modelling scenarios have been considered when developing these forecasts.

Scenario 1 projects future renewal timing and costs using the acquisition year (or date of last renewal) and useful life from Council’s asset register. This is an important aspect as it communicates what is being stated in Council’s Financial Statements and should reflect the state of the assets and remaining service potential. Instances can occur where remaining lives can be under and/or over stated which can impact valuations and subsequent depreciation allocated to the Operating Statement.

Scenario 2 is aimed at sustaining existing assets over the long term at an agreed or desired service levels. The needs are based on technical knowledge and expertise from existing systems and officers. This is the best available measure of renewal need at the present time and improvements are underway to increase the confidence in these forecasts.

Scenario 3 balances the operating, maintenance and capital renewal and upgrade/new expenditure projections identified in Scenario 2 with the available funds in the Long-term Financial Plan (LTFP) and discusses the likely service implications and risks.

The difference between Scenario 2 and 3 represents “what we can’t do”. This enables a discussion about

1 http://forecast2.id.com.au

the ‘gap’ in service delivery and will lead to a more informed discussion about what are achievable and acceptable service levels, while giving a focus on managing risk. In time, with increased knowledge of the asset stock and future needs Council will be in a more effective position to communicate these risks to the community.

What does it Cost?The projected outlays necessary to provide the services covered by this Asset Management Plan (AM Plan) includes operations, maintenance, renewal and upgrade of existing assets over the 10 year planning period is $38.3M or $3.83M on average per year.

Estimated available funding for this period is $38.3M or $3.83M on average per year which is 100% of the cost to provide the service. Projected expenditure required to provide services in the AM Plan compared with planned expenditure currently included in the Long Term Financial Plan are shown in the graph below.

What we will do

We plan to provide Street Trees services for the following: Operation, maintenance, renewal and upgrade of

streetscapes to meet service levels set by Council in annual budgets.

Confidence LevelsThis AM Plan is based on High level of confidence information.

The Next StepsThe actions resulting from this asset management plan are: To develop a prioritised streetscape renewal

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Develop and implement a process to ensure the currency of the data in the asset register (Confirm) remains up to date.

Undertake a comprehensive review of its strategic management plans within 2 years after each general election of the council.

Questions you may have

What is this plan about?This asset management plan covers the infrastructure assets that serve the City of Salisbury community’s Street Trees needs. These assets include Street Tees throughout the community area that provide amenity and shade.

What is an Asset Management Plan?Asset management planning is a comprehensive process to ensure delivery of services from infrastructure is provided in a financially sustainable manner.

An asset management plan details information about infrastructure assets including actions required to provide an agreed level of service in the most cost effective manner. The plan defines the services to be provided, how the services are provided and what funds are required to provide the services.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

2. INTRODUCTION

2.1 Background

This asset management plan is to demonstrate responsive management of assets (and services provided from assets), compliance with regulatory requirements, and to communicate funding needed to provide the required levels of service over a 20 year planning period.

The asset management plan follows the format for AM Plans recommended in Section 4.2.6 of the International Infrastructure Management Manual2.

The asset management plan is to be read with the organisation’s Asset Management Policy, Asset Management Strategy and the following associated planning documents:

City Plan Annual Plan Annual Report Community Land Management Plan

This infrastructure assets covered by this asset management plan are shown in Table 2.1. These assets are used to provide amenity and shade services to the community.

Table 2.1: Assets covered by this Plan

Asset category Dimension Replacement Value

Street Trees 75,000 (approx.) *Estimated at approx. $90M

*Note – Street Trees have historically not been valued as work was undertaken out of operating budget, this value has been calculated from an estimated replacement cost per tree.

Key stakeholders in the preparation and implementation of this asset management plan are: Shown in Table 2.1.1.

2.2 Goals and Objectives of Asset Management

The organisation exists to provide services to its community. Some of these services are provided by infrastructure assets. We have acquired infrastructure assets by ‘purchase’, by contract, construction by our staff and by donation of assets constructed by developers and others to meet increased levels of service.

Our goal in managing infrastructure assets is to meet the defined level of service (as amended from time to time) in the most cost effective manner for present and future consumers. The key elements of infrastructure asset management are:

Providing a defined level of service and monitoring performance, Managing the impact of growth through demand management and infrastructure investment, Taking a lifecycle approach to developing cost-effective management strategies for the long-term that meet

the defined level of service, Identifying, assessing and appropriately controlling risks, and

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

3.4 Levels of Service

3.4.1 Community Service Levels

Community Service levels are defined service levels in two terms, customer levels of service and technical levels of service.

Community Levels of Service measure how the community receives the service and whether the organisation is providing community value.

Community levels of service measures used in the asset management plan are:

Quality How good is the service?Function Does it meet users’ needs?Capacity/Utilisation Is the service over or under used?

3.4.2 Technical Levels of Service

Supporting the community service levels are operational or technical measures of performance. These technical measures relate to the allocation of resources to service activities that the organisation undertakes to best achieve the desired community outcomes and demonstrate effective organisational performance.

Technical service measures are linked to annual budgets covering:

Operations – the regular activities to provide services such as opening hours, cleansing, mowing grass, energy, inspections, etc.

Maintenance – the activities necessary to retain an asset as near as practicable to an appropriate service condition (eg road patching, unsealed road grading, building and structure repairs),

Renewal – the activities that return the service capability of an asset up to that which it had originally (eg frequency and cost of road resurfacing and pavement reconstruction, pipeline replacement and building component replacement),

Upgrade – the activities to provide a higher level of service (eg widening a road, sealing an unsealed road, replacing a pipeline with a larger size) or a new service that did not exist previously (eg a new library).

Service and asset managers plan, implement and control technical service levels to influence the customer service levels.6

4. FUTURE DEMAND

4.1 Demand Drivers

Drivers affecting demand include population change, changes in demographics, seasonal factors, vehicle ownership rates, consumer preferences and expectations, technological changes, economic factors, agricultural practices, environmental awareness, etc.

4.2 Demand Forecast

The present position and projections for demand drivers that may impact future service delivery and utilisation of assets were identified and are documented in Table 4.3.

6 IPWEA, 2011, IIMM, p 2.22

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

4.3 Demand Impact on Assets

The impact of demand drivers that may affect future service delivery and utilisation of assets are shown in Table 4.3.

Table 4.3: Demand Drivers, Projections and Impact on Services

Demand drivers Present position Projection Impact on services

Population 136,000 The population is forecast to grow from 136,000 to 146,000 by 2031.

Increased Assets and demand on existing assets will have a follow on impact on maintenance and renewal costs.

Urban Consolidation Allotment size on average 700m2 Allotment size following subdivision of individual allotments in isolated locations 350m2

The reduction in size of average land parcels will reduce significantly the amount of space available for a tree within the verge area. Whilst the continuing ideals of 1 street tree per frontage would result in an increase in the number of trees it is likely that in some areas this ideal may not be met

Tree Replacements Replacement of Trees that have been vandalised, damaged or died

4.4 Demand Management Plan

Demand for new services will be managed through a combination of managing existing assets, upgrading of existing assets and providing new assets to meet demand and demand management. Demand management practices include non-asset solutions, insuring against risks and managing failures.

Non-asset solutions focus on providing the required service without the need for the organisation to own the assets and management actions including reducing demand for the service, reducing the level of service (allowing some assets to deteriorate beyond current service levels) or educating customers to accept appropriate asset failures7. Examples of non-asset solutions include providing services from existing infrastructure such as aquatic centres and libraries that may be in another community area or public toilets provided in commercial premises.

4.5 Asset Programs to meet Demand

The new assets required to meet growth will be acquired free of cost from land developments and constructed/acquired by the organisation. New assets constructed/acquired by the organisation are discussed in Section 5.5

Acquiring these new assets will commit the organisation to fund ongoing operations, maintenance and renewal costs for the period that the service provided from the assets is required. These future costs are identified and considered in developing forecasts of future operations, maintenance and renewal costs in Section 5.

7 IPWEA, 2011, IIMM, Table 3.4.1, p 3|58.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

5. LIFECYCLE MANAGEMENT PLAN

The lifecycle management plan details how the organisation plans to manage and operate the assets at the agreed levels of service (defined in Section 3) while optimising life cycle costs.

5.1 Background Data

5.1.1 Physical parameters

The assets covered by this asset management plan are shown in Table 2.1.

Age profile information is not currently available. An age profile will be developed in future revisions of the asset management plan.

5.1.2 Asset capacity and performance

The organisation’s services are generally provided to meet design standards where these are available. There are no known service deficiencies.

5.1.3 Asset condition

There is no recent condition information available for street trees.

5.1.4 Asset valuations

Street Trees have historically not been capitalised and recorded in the asset register. It is estimated that the value of all street trees is approximately $90M.

5.2 Infrastructure Risk Management Plan

An assessment of risks8 associated with service delivery from infrastructure assets has identified critical risks that will result in loss or reduction in service from infrastructure assets or a ‘financial shock’ to the organisation. The risk assessment process identifies credible risks, the likelihood of the risk event occurring, the consequences should the event occur, develops a risk rating, evaluates the risk and develops a risk treatment plan for non-acceptable risks.

Critical risks, being those assessed as ‘Very High’ - requiring immediate corrective action and ‘High’ – requiring prioritised corrective action identified in the Infrastructure Risk Management Plan, together with the estimated residual risk after the selected treatment plan is operational are summarised in Table 5.2. These risks are reported to management and Council.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

5.3 Routine Operations and Maintenance Plan

Operations include regular activities to provide services such as public health, safety and amenity, eg cleansing, street sweeping, grass mowing and street lighting.

Routine maintenance is the regular on-going work that is necessary to keep assets operating, including instances where portions of the asset fail and need immediate repair to make the asset operational again.

5.3.1 Operations and Maintenance Plan

Operations activities affect service levels including quality and function for example through tree pruning frequency.

Maintenance includes all actions necessary for retaining an asset as near as practicable to an appropriate service condition including regular ongoing day-to-day work necessary to keep assets operating, eg single tree replacement but excluding full street replacement. Maintenance may be classified into reactive, planned and specific maintenance work activities.

Reactive maintenance is unplanned repair work carried out in response to service requests and management/supervisory directions.

Planned maintenance is repair work that is identified and managed through a maintenance management system (MMS). MMS activities include inspection, assessing the condition against failure/breakdown experience, prioritising, scheduling, actioning the work and reporting what was done to develop a maintenance history and improve maintenance and service delivery performance.

Specific maintenance is replacement of higher value components/sub-components of assets that is undertaken on a regular cycle including repainting, replacing air conditioning units, etc. This work falls below the capital/maintenance threshold but may require a specific budget allocation.

Maintenance expenditure levels are considered to be adequate to meet projected service levels, which may be less than or equal to current service levels. Where maintenance expenditure levels are such that will result in a lesser level of service, the service consequences and service risks have been identified and service consequences highlighted in this AM Plan and service risks considered in the Infrastructure Risk Management Plan.

Assessment and prioritisation of reactive maintenance is undertaken by Council staff using experience and judgement.

5.3.2 Operations and Maintenance Strategies

The organisation will operate and maintain assets to provide the defined level of service to approved budgets in the most cost-efficient manner. The operation and maintenance activities include:

Scheduling operations activities to deliver the defined level of service in the most efficient manner, Undertaking maintenance activities through a planned maintenance system to reduce maintenance costs and

improve maintenance outcomes. Undertake cost-benefit analysis to determine the most cost-effective split between planned and unplanned maintenance activities (50 – 70% planned desirable as measured by cost),

Maintain a current infrastructure risk register for assets and present service risks associated with providing services from infrastructure assets and reporting Very High and High risks and residual risks after treatment to management and Council,

Review current and required skills base and implement workforce training and development to meet required operations and maintenance needs,

Review asset utilisation to identify underutilised assets and appropriate remedies, and over utilised assets and customer demand management options,

Maintain a current hierarchy of critical assets and required operations and maintenance activities, Develop and regularly review appropriate emergency response capability, Review management of operations and maintenance activities to ensure Council is obtaining best value for

resources used.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Asset hierarchy

An asset hierarchy provides a framework for structuring data in an information system to assist in collection of data, reporting information and making decisions. The hierarchy includes the asset class and component used for asset planning and financial reporting and service level hierarchy used for service planning and delivery.

The organisation’s service hierarchy is shown is Table 5.3.2.

Table 5.3.2: Asset Service Hierarchy

Service Hierarchy Service Level Objective

To be developed in future revisions of the Asset Plan.

Critical Assets

Critical assets are those assets which have a high consequence of failure but not necessarily a high likelihood of failure. By identifying critical assets and critical failure modes, organisations can target and refine investigative activities, maintenance plans and capital expenditure plans at the appropriate time.

Operations and maintenance activities may be targeted to mitigate critical assets failure and maintain service levels. These activities may include increased inspection frequency, higher maintenance intervention levels, etc. Critical assets failure modes and required operations and maintenance activities are detailed in Table 5.3.2.1.

Table 5.3.2.1: Critical Assets and Service Level Objectives

Critical Assets Critical Failure Mode Operations & Maintenance Activities

To be developed in future revisions of the Asset Plan.

Standards and specifications

Maintenance work is carried out in accordance with the following Standards and Specifications.

Australian Standards AS4373 Pruning Significant Tree Legislation for Pruning AS4970 Trees on Development Sites Australian Road Rules

5.3.3 Summary of future operations and maintenance expenditures

Future operations and maintenance expenditure is forecast to trend in line with the value of the asset stock as shown in Figure 4. Note that all costs are shown in current 2015 dollar values (i.e. real values).

Deferred maintenance, ie works that are identified for maintenance and unable to be funded are to be included in the risk assessment and analysis in the infrastructure risk management plan.

Maintenance is funded from the operating budget where available. This is further discussed in Section 6.2.

5.4 Renewal/Replacement Plan

Renewal and replacement expenditure is major work which does not increase the asset’s design capacity but restores, rehabilitates, replaces or renews an existing asset to its original or lesser required service potential. Work over and above restoring an asset to original service potential is upgrade/expansion or new works expenditure.

5.4.1 Renewal plan

Assets requiring renewal/replacement are identified from one of three methods provided in the ‘Expenditure Template’.

Method 1 uses Asset Register data to project the renewal costs using acquisition year and useful life to determine the renewal year, or

Method 2 uses capital renewal expenditure projections from external condition modelling systems (such as Pavement Management Systems), or

Method 3 uses a combination of average network renewals plus defect repairs in the Renewal Plan and Defect Repair Plan worksheets on the ‘Expenditure template’.

Method 2 was used for this asset management plan.

5.4.2 Renewal and Replacement Strategies

The organisation will plan capital renewal and replacement projects to meet level of service objectives and minimise infrastructure service risks by:

Planning and scheduling renewal projects to deliver the defined level of service in the most efficient manner, Undertaking project scoping for all capital renewal and replacement projects to identify:

o the service delivery ‘deficiency’, present risk and optimum time for renewal/replacement,o the project objectives to rectify the deficiency, o the range of options, estimated capital and life cycle costs for each options that could address the

service deficiency, o and evaluate the options against evaluation criteria adopted by the organisation, ando select the best option to be included in capital renewal programs,

Using ‘low cost’ renewal methods (cost of renewal is less than replacement) wherever possible, Maintain a current infrastructure risk register for assets and service risks associated with providing services

from infrastructure assets and reporting Very High and High risks and residual risks after treatment to management and Council,

Review current and required skills base and implement workforce training and development to meet required construction and renewal needs,

Maintain a current hierarchy of critical assets and capital renewal treatments and timings required , Review management of capital renewal and replacement activities to ensure Council is obtaining best value

for resources used.

Renewal ranking criteria

Asset renewal and replacement is typically undertaken to either:

Ensure the reliability of the existing infrastructure to deliver the service it was constructed to facilitate or To ensure the infrastructure is of sufficient quality to meet the service requirements.9

It is possible to get some indication of capital renewal and replacement priorities by identifying assets or asset groups that:

Have a high consequence of failure, Have a high utilisation and subsequent impact on users would be greatest, The total value represents the greatest net value to the organisation, Have the highest average age relative to their expected lives, Are identified in the AM Plan as key cost factors, Have high operational or maintenance costs, and Where replacement with modern equivalent assets would yield material savings.10

The ranking criteria used to determine priority of identified renewal and replacement proposals is detailed in Table 5.4.2.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Renewals and replacement expenditure in the organisation’s capital works program will be accommodated in the long term financial plan. This is further discussed in Section 6.2.

5.5 Creation/Acquisition/Upgrade Plan

New works are those works that create a new asset that did not previously exist, or works which upgrade or improve an existing asset beyond its existing capacity. They may result from growth, social or environmental needs. Assets may also be acquired at no cost to the organisation from land development. These assets from growth are considered in Section 4.4.

5.5.1 Selection criteria

New assets and upgrade/expansion of existing assets are identified from various sources such as councillor/director or community requests, proposals identified by strategic plans or partnerships with other organisations. Candidate proposals are inspected to verify need and to develop a preliminary renewal estimate. Verified proposals are ranked by priority and available funds and scheduled in future works programmes. The priority ranking criteria is detailed below.

5.5.2 Capital Investment Strategies

The organisation will plan capital upgrade and new projects to meet level of service objectives by:

Planning and scheduling capital upgrade and new projects to deliver the defined level of service in the most efficient manner,

Undertake project scoping for all capital upgrade/new projects to identify:o the service delivery ‘deficiency’, present risk and required timeline for delivery of the upgrade/new

asset,o the project objectives to rectify the deficiency including value management for major projects,o the range of options, estimated capital and life cycle costs for each options that could address the

service deficiency, o management of risks associated with alternative options,o and evaluate the options against evaluation criteria adopted by Council, ando select the best option to be included in capital upgrade/new programs,

Review current and required skills base and implement training and development to meet required construction and project management needs,

Review management of capital project management activities to ensure Council is obtaining best value for resources used.

Standards and specifications for new assets and for upgrade/expansion of existing assets are the same as those for renewal shown in Section 5.4.2.

5.5.3 Summary of future upgrade/new assets expenditure

There is currently no planned upgrade/new expenditure for street trees.

Expenditure on new assets and services in the organisation’s capital works program will be accommodated in the long term financial plan. This is further discussed in Section 6.2.

5.6 Disposal Plan

Disposal includes any activity associated with disposal of a decommissioned asset including sale, demolition or relocation. Assets identified for possible decommissioning and disposal are shown in Table 5.6, together with estimated annual savings from not having to fund operations and maintenance of the assets. These assets will be further reinvestigated to determine the required levels of service and see what options are available for alternate service delivery, if any. Any revenue gained from asset disposals is accommodated in Council’s long term financial plan.

Where cash flow projections from asset disposals are not available, these will be developed in future revisions of this asset management plan.

5.7 Service Consequences and Risks

The organisation has prioritised decisions made in adopting this AM Plan to obtain the optimum benefits from its available resources. Decisions were made based on the development of 3 scenarios of AM Plans.

Scenario 1 - What we would like to do based on asset register data

Scenario 2 – What we should do with existing budgets and identifying level of service and risk consequences (ie what are the operations and maintenance and capital projects we are unable to do, what is the service and risk consequences associated with this position). This may require several versions of the AM Plan.

Scenario 3 – What we can do and be financially sustainable with AM Plans matching long-term financial plans.

The development of scenario 1 and scenario 2 AM Plans provides the tools for discussion with the Council and community on trade-offs between what we would like to do (scenario 1) and what we should be doing with existing budgets (scenario 2) by balancing changes in services and service levels with affordability and acceptance of the service and risk consequences of the trade-off position (scenario 3).

5.7.1 What we cannot do

There are some operations and maintenance activities and capital projects that are unable to be undertaken within the next 10 years. These include:

Increasing the streetscape renewal program by $404,000 to increase the rate at which streetscapes are renewed.

The Transportation asset management plan indicates that footpath maintenance could be reduced by $400,000 by reducing the amount of proactive faults repaired to fund an increase in the streetscape renewal program. The decrease in the footpath maintenance program must be linked to an increase in the streetscape program as increasing the rate of tree renewal should see a reduction in the number of footpath faults leading to lower maintenance costs in the long term.

5.7.2 Service consequences

If current budgets are maintained then there will be little discernible impact upon the community.

- 24 -

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

5.7.3 Risk consequences

The operations and maintenance activities and capital projects that cannot be undertaken may maintain or create risk consequences for the organisation. These include:

Continued higher maintenance/renewal costs for infrastructure assets (eg footpath, kerbing and roads etc.) Continued risk of footpath trips occurring

These risks have been included with the Infrastructure Risk Management Plan summarised in Section 5.2 and risk management plans actions and expenditures included within projected expenditures.

6. FINANCIAL SUMMARYThis section contains the financial requirements resulting from all the information presented in the previous sections of this asset management plan. The financial projections will be improved as further information becomes available on desired levels of service and current and projected future asset performance.

6.1 Financial Statements and Projections

The financial projections are shown in Fig 7 for projected operating (operations and maintenance) and capital expenditure (renewal and upgrade/expansion/new assets). Note that all costs are shown in real values.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

6.1.1 Sustainability of service delivery

There are four key indicators for service delivery sustainability that have been considered in the analysis of the services provided by this asset category, these being the asset renewal funding ratio, long term life cycle costs/expenditures and medium term projected/budgeted expenditures over 5 and 10 years of the planning period.

Asset Renewal Funding Ratio

Asset Renewal Funding Ratio11 100%

The Asset Renewal Funding Ratio is the most important indicator and reveals that over the next 10 years, Council is forecasting that it will have 100% of the funds required for the optimal renewal and replacement of its assets (based on scenario 3).

Long term - Life Cycle Cost

Life cycle costs (or whole of life costs) are the average costs that are required to sustain the service levels over the asset life cycle. Life cycle costs include operations and maintenance expenditure and asset consumption (depreciation expense). The life cycle cost for the services covered in this asset management plan is $2.73M per year (average operations and maintenance expenditure plus depreciation expense projected over 10 years).

Life cycle costs can be compared to life cycle expenditure to give an initial indicator of affordability of projected service levels when considered with age profiles. Life cycle expenditure includes operations, maintenance and capital renewal expenditure. Life cycle expenditure will vary depending on the timing of asset renewals. The life cycle expenditure over the 10 year planning period is $3.83M per year (average operations and maintenance plus capital renewal budgeted expenditure in LTFP over 10 years).

A shortfall between life cycle cost and life cycle expenditure is the life cycle gap. The life cycle gap for services covered by this asset management plan is +$1.1M per year (-ve = gap, +ve = surplus).

Life cycle expenditure is 140% of life cycle costs.

The life cycle costs and life cycle expenditure comparison highlights any difference between present outlays and the average cost of providing the service over the long term. If the life cycle expenditure is less than that life cycle cost, it is most likely that outlays will need to be increased or cuts in services made in the future.

Knowing the extent and timing of any required increase in outlays and the service consequences if funding is not available will assist organisations in providing services to their communities in a financially sustainable manner. This is the purpose of the asset management plans and long term financial plan.

Medium term – 10 year financial planning period

This asset management plan identifies the projected operations, maintenance and capital renewal expenditures required to provide an agreed level of service to the community over a 10 year period. This provides input into 10 year financial and funding plans aimed at providing the required services in a sustainable manner.

These projected expenditures may be compared to budgeted expenditures in the 10 year period to identify any funding shortfall. In a core asset management plan, a gap is generally due to increasing asset renewals for ageing assets.

The projected operations, maintenance and capital renewal expenditure required over the 10 year planning period is $3.83M on average per year.

- 26 -

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Estimated (budget) operations, maintenance and capital renewal funding is $3.837M on average per year giving a 10 year funding shortfall of $0.00 per year. This indicates that Council expects to have 100% of the projected expenditures needed to provide the services documented in the asset management plan.

Medium Term – 5 year financial planning period

The projected operations, maintenance and capital renewal expenditure required over the first 5 years of the planning period is $3.83M on average per year.

Estimated (budget) operations, maintenance and capital renewal funding is $3.83M on average per year giving a 5 year funding shortfall of $0. This indicates that Council expects to have 100% of projected expenditures required to provide the services shown in this asset management plan.

Asset management financial indicators

Figure 7A shows the asset management financial indicators over the 10 year planning period and for the long term life cycle.

Figure 7A: Asset Management Financial Indicators

Providing services from infrastructure in a sustainable manner requires the matching and managing of service levels, risks, projected expenditures and financing to achieve a financial indicator of approximately 1.0 for the first years of the asset management plan and ideally over the 10 year life of the Long Term Financial Plan.

Figure 8 shows the projected asset renewal and replacement expenditure over the 20 years of the AM Plan. The projected asset renewal and replacement expenditure is compared to renewal and replacement expenditure in the capital works program, which is accommodated in the long term financial plan

2035 $1,100 $1,100 $0 $0Note: A negative shortfall indicates a financing gap, a positive shortfall indicates a surplus for that year.

Providing services in a sustainable manner will require matching of projected asset renewal and replacement expenditure to meet agreed service levels with the corresponding capital works program accommodated in the long term financial plan.

A gap between projected asset renewal/replacement expenditure and amounts accommodated in the LTFP indicates that further work is required on reviewing service levels in the AM Plan (including possibly revising the LTFP) before finalising the asset management plan to manage required service levels and funding to eliminate any funding gap.

We will manage the ‘gap’ by developing this asset management plan to provide guidance on future service levels and resources required to provide these services, and review future services, service levels and costs with the community.

6.2 Funding Strategy

After reviewing service levels, as appropriate to ensure ongoing financial sustainability projected expenditures identified in Section 6.1.2 will be accommodated in the Council’s 10 year long term financial plan.

6.3 Valuation Forecasts

Historically street trees have not been capitalised as works were undertaken out of operating budgets, therefore valuation forecasts are unavailable to be reported for street trees. Street trees will be capitalised from 2014/15 as projects are completed so this will be improved in future iterations of this asset management plan.

6.4 Key Assumptions made in Financial Forecasts

This section details the key assumptions made in presenting the information contained in this asset management plan and in preparing forecasts of required operating and capital expenditure and asset values, depreciation expense and carrying amount estimates. It is presented to enable readers to gain an understanding of the levels of confidence in the data behind the financial forecasts.

Key assumptions made in this asset management plan and risks that these may change are shown in Table 6.4.

Table 6.4: Key Assumptions made in AM Plan and Risks of Change

Key Assumptions Risks of Change to AssumptionsThe cost to supply install and establish a street tree is approximately $1,250 per tree

Desired funding in scenario 2 may change if calculated unit rate is updated/recalculated.

The number of street trees in the city has been maintained at 75,000 since an audit in 2005/06

Required renewal for scenario 2 may change if number of trees has declined since the previous audit.

6.5 Forecast Reliability and Confidence

The expenditure and valuations projections in this AM Plan are based on best available data. Currency and accuracy of data is critical to effective asset and financial management. Data confidence is classified on a 5 level scale12 in accordance with Table 6.5.

Table 6.5: Data Confidence Grading System

7. PLAN IMPROVEMENT AND MONITORING

7.1 Status of Asset Management Practices

7.1.1 Accounting and financial systems

Council uses ‘Finance One’ as its corporate financial system which is administered through the Finance Department. No changes are proposed to accounting / financial systems as part of this AMP.

Accountabilities for financial systems

The General Manager Business Excellence is responsible for all financial systems within the City of Salisbury. They have a team of staff to assist in the process that is also subject to internal and external audits.

Accounting standards and regulations

Guidance in recognising and reporting on assets is provided by Australian Accounting Standards

Capital/maintenance threshold

Council’s capital threshold is $5,000 for street trees.

7.1.2 Asset management system

The City of Salisbury uses ‘Confirm’ as its Asset Management System.

Linkage from asset management to financial system

Confirm is linked to ‘Finance One,’ Councils corporate finance system via a manual batch process, Fleet 5 is linked via the Fleet Ledger

Accountabilities for asset management system and data maintenance

Confirm is administered through the City Infrastructure Departments Business Support division and has a full time coordinator responsible for its implementation. Data entry on a job by job (maintenance) basis is handled via several staff within Councils Business Support division.

7.3 Monitoring and Review Procedures

This asset management plan will be reviewed during annual budget planning processes and amended to recognise any material changes in service levels and/or resources available to provide those services as a result of budget decisions.

The AM Plan will be updated annually to ensure it represents the current service level, asset values, projected operations, maintenance, capital renewal and replacement, capital upgrade/new and asset disposal expenditures and projected expenditure values incorporated into the organisation’s long term financial plan.

The AM Plan has a life of 4 years (Council election cycle) and is due for complete revision and updating on an annual basis to align with the budget process and review of the Long Term Financial Plan.

7.4 Performance Measures

The effectiveness of the asset management plan can be measured in the following ways:

The degree to which the required projected expenditures identified in this asset management plan are incorporated into Council’s long term financial plan,

The degree to which 1-5 year detailed works programs, budgets, business plans and organisational structures take into account the ‘global’ works program trends provided by the asset management plan,

The degree to which the existing and projected service levels and service consequences (what we cannot do), risks and residual risks are incorporated into the Council’s Strategic Plan and associated plans,

The Asset Renewal Funding Ratio achieving the target of 1.0.

Appendix F Glossary

Annual service cost (ASC)1) Reporting actual cost The annual (accrual) cost of providing a service

including operations, maintenance, depreciation, finance/opportunity and disposal costs less revenue.

2) For investment analysis and budgeting An estimate of the cost that would be tendered,

per annum, if tenders were called for the supply of a service to a performance specification for a fixed term. The Annual Service Cost includes operations, maintenance, depreciation, finance/ opportunity and disposal costs, less revenue.

AssetA resource controlled by an entity as a result of past events and from which future economic benefits are expected to flow to the entity. Infrastructure assets are a sub-class of property, plant and equipment which are non-current assets with a life greater than 12 months and enable services to be provided.

Asset categorySub-group of assets within a class hierarchy for financial reporting and management purposes.

Asset classA group of assets having a similar nature or function in the operations of an entity, and which, for purposes of disclosure, is shown as a single item without supplementary disclosure.

Asset condition assessmentThe process of continuous or periodic inspection, assessment, measurement and interpretation of the resultant data to indicate the condition of a specific asset so as to determine the need for some preventative or remedial action.

Asset hierarchyA framework for segmenting an asset base into appropriate classifications. The asset hierarchy can be based on asset function or asset type or a combination of the two.

Asset management (AM)The combination of management, financial, economic, engineering and other practices applied to physical assets with the objective of providing the required level of service in the most cost effective manner.

Asset renewal funding ratioThe ratio of the net present value of asset renewal funding accommodated over a 10 year period in a long term financial plan relative to the net present value of projected capital renewal expenditures identified in an asset management plan for the same period [AIFMG Financial Sustainability Indicator No 8].

Average annual asset consumption (AAAC)*The amount of an organisation’s asset base consumed during a reporting period (generally a year). This may be calculated by dividing the depreciable amount by the useful life (or total future economic benefits/service potential) and totalled for each and every asset OR by dividing the carrying amount (depreciated replacement cost) by the remaining useful life (or remaining future economic benefits/service potential) and totalled for each and every asset in an asset category or class.

BorrowingsA borrowing or loan is a contractual obligation of the borrowing entity to deliver cash or another financial asset to the lending entity over a specified period of time or at a specified point in time, to cover both the initial capital provided and the cost of the interest incurred for providing this capital. A borrowing or loan provides the means for the borrowing entity to finance outlays (typically physical assets) when it has insufficient funds of its own to do so, and for the lending entity to make a financial return, normally in the form of interest revenue, on the funding provided.

Capital expenditureRelatively large (material) expenditure, which has benefits, expected to last for more than 12 months. Capital expenditure includes renewal, expansion and upgrade. Where capital projects involve a combination of renewal, expansion and/or upgrade expenditures, the total project cost needs to be allocated accordingly.

Capital expenditure - expansionExpenditure that extends the capacity of an existing asset to provide benefits, at the same standard as is currently enjoyed by existing beneficiaries, to a new group of users. It is discretionary expenditure, which increases future operations and maintenance costs, because it increases the organisation’s asset base, but may be associated with additional revenue from the new user group, eg. extending a drainage or road network, the provision of an oval or park in a new suburb for new residents.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Capital expenditure - newExpenditure which creates a new asset providing a new service/output that did not exist beforehand. As it increases service potential it may impact revenue and will increase future operations and maintenance expenditure.

Capital expenditure - renewalExpenditure on an existing asset or on replacing an existing asset, which returns the service capability of the asset up to that which it had originally. It is periodically required expenditure, relatively large (material) in value compared with the value of the components or sub-components of the asset being renewed. As it reinstates existing service potential, it generally has no impact on revenue, but may reduce future operations and maintenance expenditure if completed at the optimum time, eg. resurfacing or resheeting a material part of a road network, replacing a material section of a drainage network with pipes of the same capacity, resurfacing an oval.

Capital expenditure - upgradeExpenditure, which enhances an existing asset to provide a higher level of service or expenditure that will increase the life of the asset beyond that which it had originally. Upgrade expenditure is discretionary and often does not result in additional revenue unless direct user charges apply. It will increase operations and maintenance expenditure in the future because of the increase in the organisation’s asset base, eg. widening the sealed area of an existing road, replacing drainage pipes with pipes of a greater capacity, enlarging a grandstand at a sporting facility.

Capital fundingFunding to pay for capital expenditure.

Capital grantsMonies received generally tied to the specific projects for which they are granted, which are often upgrade and/or expansion or new investment proposals.

Capital investment expenditureSee capital expenditure definition

Capitalisation thresholdThe value of expenditure on non-current assets above which the expenditure is recognised as capital expenditure and below which the expenditure is charged as an expense in the year of acquisition.

Carrying amountThe amount at which an asset is recognised after deducting any accumulated depreciation / amortisation and accumulated impairment losses thereon.

Class of assetsSee asset class definition

ComponentSpecific parts of an asset having independent physical or functional identity and having specific attributes such as different life expectancy, maintenance regimes, risk or criticality.

Core asset management Asset management which relies primarily on the use of an asset register, maintenance management systems, job resource management, inventory control, condition assessment, simple risk assessment and defined levels of service, in order to establish alternative treatment options and long-term cashflow predictions. Priorities are usually established on the basis of financial return gained by carrying out the work (rather than detailed risk analysis and optimised decision- making).

Cost of an assetThe amount of cash or cash equivalents paid or the fair value of the consideration given to acquire an asset at the time of its acquisition or construction, including any costs necessary to place the asset into service. This includes one-off design and project management costs.

Critical assetsAssets for which the financial, business or service level consequences of failure are sufficiently severe to justify proactive inspection and rehabilitation. Critical assets have a lower threshold for action than non-critical assets.

Current replacement cost (CRC)The cost the entity would incur to acquire the asset on the reporting date. The cost is measured by reference to the lowest cost at which the gross future economic benefits could be obtained in the normal course of business or the minimum it would cost, to replace the existing asset with a technologically modern equivalent new asset (not a second hand one) with the same economic benefits (gross service potential) allowing for any differences in the quantity and quality of output and in operating costs.

Deferred maintenance The shortfall in rehabilitation work undertaken relative to that required to maintain the service potential of an asset.

Depreciable amountThe cost of an asset, or other amount substituted for its cost, less its residual value.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Depreciated replacement cost (DRC)The current replacement cost (CRC) of an asset less, where applicable, accumulated depreciation calculated on the basis of such cost to reflect the already consumed or expired future economic benefits of the asset.

Depreciation / amortisationThe systematic allocation of the depreciable amount (service potential) of an asset over its useful life.

Economic lifeSee useful life definition.

ExpenditureThe spending of money on goods and services. Expenditure includes recurrent and capital outlays.

ExpensesDecreases in economic benefits during the accounting period in the form of outflows or depletions of assets or increases in liabilities that result in decreases in equity, other than those relating to distributions to equity participants.

Fair valueThe amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties, in an arms length transaction.

Financing gapA financing gap exists whenever an entity has insufficient capacity to finance asset renewal and other expenditure necessary to be able to appropriately maintain the range and level of services its existing asset stock was originally designed and intended to deliver. The service capability of the existing asset stock should be determined assuming no additional operating revenue, productivity improvements, or net financial liabilities above levels currently planned or projected. A current financing gap means service levels have already or are currently falling. A projected financing gap if not addressed will result in a future diminution of existing service levels.

Heritage assetAn asset with historic, artistic, scientific, technological, geographical or environmental qualities that is held and maintained principally for its contribution to knowledge and culture and this purpose is central to the objectives of the entity holding it.

Impairment LossThe amount by which the carrying amount of an asset exceeds its recoverable amount.

Infrastructure assetsPhysical assets that contribute to meeting the needs of organisations or the need for access to major economic and social facilities and services, eg. roads, drainage, footpaths and cycleways. These are typically large, interconnected networks or portfolios of composite assets. The components of these assets may be separately maintained, renewed or replaced individually so that the required level and standard of service from the network of assets is continuously sustained. Generally the components and hence the assets have long lives. They are fixed in place and are often have no separate market value.

Investment propertyProperty held to earn rentals or for capital appreciation or both, rather than for:(a) use in the production or supply of goods or services

or for administrative purposes; or(b) sale in the ordinary course of business.

Key performance indicator A qualitative or quantitative measure of a service or activity used to compare actual performance against a standard or other target. Performance indicators commonly relate to statutory limits, safety, responsiveness, cost, comfort, asset performance, reliability, efficiency, environmental protection and customer satisfaction.

Level of serviceThe defined service quality for a particular service/activity against which service performance may be measured. Service levels usually relate to quality, quantity, reliability, responsiveness, environmental impact, acceptability and cost.

Life Cycle Cost *1. Total LCC The total cost of an asset throughout its

life including planning, design, construction, acquisition, operation, maintenance, rehabilitation and disposal costs.

2. Average LCC The life cycle cost (LCC) is average cost to provide the service over the longest asset life cycle. It comprises average operations, maintenance expenditure plus asset consumption expense, represented by depreciation expense projected over 10 years. The Life Cycle Cost does not indicate the funds required to provide the service in a particular year.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Life Cycle ExpenditureThe Life Cycle Expenditure (LCE) is the average operations, maintenance and capital renewal expenditure accommodated in the long term financial plan over 10 years. Life Cycle Expenditure may be compared to average Life Cycle Cost to give an initial indicator of affordability of projected service levels when considered with asset age profiles.

Loans / borrowingsSee borrowings.

Maintenance All actions necessary for retaining an asset as near as practicable to an appropriate service condition, including regular ongoing day-to-day work necessary to keep assets operating, eg road patching but excluding rehabilitation or renewal. It is operating expenditure required to ensure that the asset reaches its expected useful life.• Planned maintenance

Repair work that is identified and managed through a maintenance management system (MMS). MMS activities include inspection, assessing the condition against failure/breakdown criteria/experience, prioritising scheduling, actioning the work and reporting what was done to develop a maintenance history and improve maintenance and service delivery performance.

• Reactive maintenanceUnplanned repair work that is carried out in response to service requests and management/ supervisory directions.

• Specific maintenanceMaintenance work to repair components or replace sub-components that needs to be identified as a specific maintenance item in the maintenance budget.

• Unplanned maintenance Corrective work required in the short-term to restore an asset to working condition so it can continue to deliver the required service or to maintain its level of security and integrity.

Maintenance expenditure *Recurrent expenditure, which is periodically or regularly required as part of the anticipated schedule of works required to ensure that the asset achieves its useful life and provides the required level of service. It is expenditure, which was anticipated in determining the asset’s useful life.

MaterialityThe notion of materiality guides the margin of error acceptable, the degree of precision required and the extent of the disclosure required when preparing general purpose financial reports. Information is material if its omission, misstatement or non-disclosure has the potential, individually or collectively, to influence the economic decisions of users taken on the basis of the financial report or affect the discharge of accountability by the management or governing body of the entity.

Modern equivalent assetAssets that replicate what is in existence with the most cost-effective asset performing the same level of service. It is the most cost efficient, currently available asset which will provide the same stream of services as the existing asset is capable of producing. It allows for technology changes and, improvements and efficiencies in production and installation techniques

Net present value (NPV) The value to the organisation of the cash flows associated with an asset, liability, activity or event calculated using a discount rate to reflect the time value of money. It is the net amount of discounted total cash inflows after deducting the value of the discounted total cash outflows arising from eg the continued use and subsequent disposal of the asset after deducting the value of the discounted total cash outflows.

Non-revenue generating investmentsInvestments for the provision of goods and services to sustain or improve services to the community that are not expected to generate any savings or revenue to the Council, eg. parks and playgrounds, footpaths, roads and bridges, libraries, etc.

OperationsRegular activities to provide services such as public health, safety and amenity, eg street sweeping, grass mowing and street lighting.

Operating expenditureRecurrent expenditure, which is continuously required to provide a service. In common use the term typically includes, eg power, fuel, staff, plant equipment, on-costs and overheads but excludes maintenance and depreciation. Maintenance and depreciation is on the other hand included in operating expenses.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Operating expenseThe gross outflow of economic benefits, being cash and non cash items, during the period arising in the course of ordinary activities of an entity when those outflows result in decreases in equity, other than decreases relating to distributions to equity participants.

Operating expensesRecurrent expenses continuously required to provide a service, including power, fuel, staff, plant equipment, maintenance, depreciation, on-costs and overheads.

Operations, maintenance and renewal financing ratioRatio of estimated budget to projected expenditure for operations, maintenance and renewal of assets over a defined time (eg 5, 10 and 15 years).

Operations, maintenance and renewal gapDifference between budgeted expenditures in a long term financial plan (or estimated future budgets in absence of a long term financial plan) and projected expenditures for operations, maintenance and renewal of assets to achieve/maintain specified service levels, totalled over a defined time (e.g. 5, 10 and 15 years).

Pavement management system (PMS)A systematic process for measuring and predicting the condition of road pavements and wearing surfaces over time and recommending corrective actions.

PMS ScoreA measure of condition of a road segment determined from a Pavement Management System.

Rate of annual asset consumption *The ratio of annual asset consumption relative to the depreciable amount of the assets. It measures the amount of the consumable parts of assets that are consumed in a period (depreciation) expressed as a percentage of the depreciable amount.

Rate of annual asset renewal *The ratio of asset renewal and replacement expenditure relative to depreciable amount for a period. It measures whether assets are being replaced at the rate they are wearing out with capital renewal expenditure expressed as a percentage of depreciable amount (capital renewal expenditure/DA).

Rate of annual asset upgrade/new *A measure of the rate at which assets are being upgraded and expanded per annum with capital upgrade/new expenditure expressed as a percentage of depreciable amount (capital upgrade/expansion expenditure/DA).

Recoverable amountThe higher of an asset's fair value, less costs to sell and its value in use.

Recurrent expenditureRelatively small (immaterial) expenditure or that which has benefits expected to last less than 12 months. Recurrent expenditure includes operations and maintenance expenditure.

Recurrent fundingFunding to pay for recurrent expenditure.

RehabilitationSee capital renewal expenditure definition above.

Remaining useful lifeThe time remaining until an asset ceases to provide the required service level or economic usefulness. Age plus remaining useful life is useful life.

RenewalSee capital renewal expenditure definition above.

Residual valueThe estimated amount that an entity would currently obtain from disposal of the asset, after deducting the estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life.

Revenue generating investmentsInvestments for the provision of goods and services to sustain or improve services to the community that are expected to generate some savings or revenue to offset operating costs, eg public halls and theatres, childcare centres, sporting and recreation facilities, tourist information centres, etc.

Risk management The application of a formal process to the range of possible values relating to key factors associated with a risk in order to determine the resultant ranges of outcomes and their probability of occurrence.

Section or segmentA self-contained part or piece of an infrastructure asset.

Service potentialThe total future service capacity of an asset. It is normally determined by reference to the operating capacity and economic life of an asset. A measure of service potential is used in the not-for-profit sector/public sector to value assets, particularly those not producing a cash flow.

CITY OF SALISBURY – STREET TREES ASSET MANAGEMENT PLAN

Service potential remainingA measure of the future economic benefits remaining in assets. It may be expressed in dollar values (Fair Value) or as a percentage of total anticipated future economic benefits. It is also a measure of the percentage of the asset’s potential to provide services that is still available for use in providing services (Depreciated Replacement Cost/Depreciable Amount).

Specific MaintenanceReplacement of higher value components/sub-components of assets that is undertaken on a regular cycle including repainting, replacement of air conditioning equipment, etc. This work generally falls below the capital/ maintenance threshold and needs to be identified in a specific maintenance budget allocation.

Strategic Longer-Term Plan A plan covering the term of office of councillors (4 years minimum) reflecting the needs of the community for the foreseeable future. It brings together the detailed requirements in the Council’s longer-term plans such as the asset management plan and the long-term financial plan. The plan is prepared in consultation with the community and details where the Council is at that point in time, where it wants to go, how it is going to get there, mechanisms for monitoring the achievement of the outcomes and how the plan will be resourced.

Sub-componentSmaller individual parts that make up a component part.

Useful lifeEither:(a) the period over which an asset is expected to be

available for use by an entity, or(b) the number of production or similar units expected

to be obtained from the asset by the entity.It is estimated or expected time between placing the asset into service and removing it from service, or the estimated period of time over which the future economic benefits embodied in a depreciable asset, are expected to be consumed by the Council.

Value in UseThe present value of future cash flows expected to be derived from an asset or cash generating unit. It is deemed to be depreciated replacement cost (DRC) for those assets whose future economic benefits are not primarily dependent on the asset's ability to generate net cash inflows, where the entity would, if deprived of the asset, replace its remaining future economic benefits.
